Provided herein are devices, systems, and methods for measuring waste material weight within two or more waste collection bins The bins can be measured using one or more waste measurement devices, and the measurements can be collected and transmitted to networked data storage. Waste measurement data can be collected over time from multiple bin locations, and the stored data can be analyzed and processed to generate reports and ratings of waste collection, disposal, and diversion trends over time. Also provided are waste audit methods and platforms that simplify and streamline data measurement, recording, and analyzing. The audit methods can transfer data electronically to a computer or cloud platform, automatically plot and compare results, and generate reports to be shared with a user or client.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A waste measurement device comprising: a platform having an upper surface and a lower surface; an array of two or more load cells, wherein each load cell has a top and a bottom, wherein each load cell top is in mechanical connection with the lower surface of the platform, and wherein the array of load cells defines two or more measurement areas on the upper surface of the platform; a base connected to each load cell bottom; two or more bins, wherein each bin has a floor and one or more bin walls, wherein the bin walls of each one of the two or more bins are connected to the floor of the bin, wherein the floor and bin walls of each one of the two or more bins define a chamber configured to receive waste material, wherein each of the two or more bins is configured to be removably positioned on one of the measurement areas of the upper surface of the platform, and wherein the load cells are configured to generate electrical signals having magnitudes proportional to weights of waste material within the chambers of the two or more bins; an amplifier configured to amplify the electrical signals generated by the two or more load cells; a processor configured to convert the amplified electrical signals into a digital signal; and a communicator configured to wirelessly transmit the digital signal.
2. The waste measurement device of claim 1 , further comprising: a bearing in mechanical connection with the lower surface of the platform and the base, wherein the bearing is configured to allow the platform to rotate relative to the base.
3. The waste measurement device of claim 1 , further comprising: a ramp connected to the platform.
4. The waste measurement device of claim 1 , wherein the platform is adjustably extendable in at least one dimension.
5. The waste measurement device of claim 1 , further comprising: four or more straps mechanically connected to the platform and configured to releasably secure the bins to the platform when the bins are positioned on the measurement areas of the platform.
6. The waste measurement device of claim 1 , further comprising: one or more shock absorbers mechanically connected to the platform and the base.
7. The waste measurement device of claim 1 , wherein the amplifier, processor, and communicator are each integrated into the platform, the base, or one or both of the two or more bins.
8. A waste measurement system comprising: two or more waste measurement devices of claim 1 ; and a controller configured to receive the digital signals transmitted from the two or more waste measurement devices, and to wirelessly broadcast data based on the received digital signals.
9. A method for measuring waste, the method comprising: providing a waste measuring system comprising a sensing unit, a data collection unit, a display unit, and a data storage unit; providing a waste container, wherein the waste container is at least partially filled with a waste material, and wherein the waste material comprises a waste type; communicating to the waste measuring system a waste category corresponding to the waste type, thereby generating waste category data associated with the waste material; quantifying the weight of the waste container, in response to the communicating, and using the sensing unit, thereby generating waste weight data associated with the waste material; transmitting the waste category data and the waste weight data to the data collection unit using the sensing unit; and presenting the waste category data and the waste weight data using the display unit.
10. The method of claim 9 , wherein the sensing unit comprises a scale.
11. The method of claim 9 , wherein the sensing unit comprises the waste measurement device of claim 1 .
12. The method of claim 9 , wherein the communicating of the waste category comprises entering a command using the sensing unit.
13. The method of claim 9 , wherein the communicating of the waste category comprises entering a command using the data collection unit.
14. The method of claim 12 , wherein the entering of the command comprises touching a button or switch, or speaking a voice prompt.
15. The method of claim 9 , wherein the data collection unit is a computer system.
16. The method of claim 15 , wherein the computer system is a mobile device.
17. The method of claim 9 , wherein the display unit is the sensing unit.
18. The method of claim 9 , wherein the display unit is the data collection unit.
19. The method of claim 9 , wherein the waste container is a first waste container, wherein the waste material is a first waste material, wherein the waste type is a first waste type, wherein the waste category is a first waste category, and wherein the method further comprises: providing a second waste container, wherein the second waste container is at least partially filled with a second waste material, and wherein the second waste material comprises a second waste type; inputting to the waste measuring system a second waste category corresponding to the second waste type, thereby generating waste category data associated with the second waste material; quantifying the weight of the second waste container, in response to the inputting, and using the sensing unit, thereby generating waste weight data associated with the second waste material; transmitting the waste category data and the waste weight data to the data collection unit using the sensing unit; and producing a report comprising waste category data and waste weight data associated with the first waste material and the second waste material.
20. A method for categorizing a waste generator, the method comprising: acquiring a plurality of images of waste containers associated with the waste generator, wherein the images are acquired at two or more times during a selected time period; estimating, based on the plurality of images, a total volume of waste generated by waste generator during the selected time period; identifying, based on the plurality of images, common waste material types in the total volume of waste generated during the selected time period; deriving, using a statistical model, a waste generator score for the waste generator during the selected time period based on the estimated total volume of waste generated and the identified common waste material types; and assigning the waste generator to a category based on the derived waste generator score.
